WebBy using the converse of Pythagoras' theorem, it suffices to show that OP2 + MP2 = OM2. We have that OP2 = OA ⋅ OA ′ = (OB − AB)(OB + AB) = OB2 − AB2 = (OM2 − MB2) − AB2 = OM2 − (MB2 + AB2) = OM2 − MA2 = OM2 − MP2. Hence, any circle through a point A and its inverted point A ′ is perpendicular to the inversion circle.
